The Barber Colman M573-5108 is a pneumatic damper actuator engineered for precise modulating control in HVAC systems. Designed to respond to standard pneumatic signals, this actuator offers proportional control over airflow through ventilation dampers or control valves. It includes a spring return feature, ensuring fail-safe positioning when control pressure is lost. Ideal for use in commercial and industrial buildings, the M573-5108 is built to deliver reliable performance and long service life.
